This new app may free Galaxy Watch owners from Samsung’s phone-locked features

A new application called the GeminiMan Wellness Companion has been developed for Galaxy Watch users by Dante63, who previously created a patched version of the Samsung Health Monitor. The app allows users to record electrocardiogram (ECG) data from the Galaxy Watch, providing detailed reports and AI-driven analysis through a mobile app. It can track heart rhythm and rate, flagging abnormal rhythms, which the Samsung Health Monitor does not. Users can personalize their measurements with notes and create multiple profiles for different users. The app ensures data security through encryption and offers export options for ECG reports in CSV or PDF formats. Future updates will include blood pressure recording and additional health metrics like blood oxygen levels and sleep patterns. The development roadmap is available on the GeminiMan Wellness Companion GitHub page.

Bitchat Review: How Jack Dorsey’s Private Offline Messenger Works

Bitchat employs the Noise Protocol Framework, specifically the XX pattern, for encrypted and authenticated communication. The Android version uses X25519 for key exchange and AES-256-GCM for message encryption. Bitchat operates without a central infrastructure, phone numbers, or traditional accounts, which reduces data collection and risks of censorship and surveillance. The app relies on Bluetooth connectivity, requiring physical proximity between users, which can enhance security but may lead to device identification. Metadata about nearby devices and connection instances may still be retained. Bitchat has not yet undergone a comprehensive external security audit, raising concerns despite its focus on privacy and encryption.

The FBI Warns That Foreign Cybercriminals Have Targeted Messaging App Users

Cybercriminals connected to Russian intelligence are conducting a large phishing campaign targeting messaging applications, impacting thousands of accounts worldwide. A joint advisory from the FBI and CISA reveals that these attacks focus on individuals with access to sensitive information, including government officials, military personnel, political figures, and journalists. The campaign relies on deception, with attackers impersonating official support channels on platforms like Signal, sending messages that prompt victims to click malicious links or provide confidential information. Victims who comply risk losing control of their accounts, allowing attackers to read private messages and access contact lists. This trend has been observed not only in the U.S. but also in the Netherlands, where similar tactics are used against government employees. The FBI notes that the security of the messaging apps is not the issue; rather, the vulnerability lies in human error. The rise of social engineering tactics poses a risk to both high-profile individuals and potentially everyday users, and users are advised to be cautious with unsolicited messages and not to share sensitive information.

ResokerRAT Hijacks Telegram API to Command Infected Windows PCs

A newly discovered Windows malware called ResokerRAT uses Telegram’s Bot API for its command-and-control operations, allowing it to monitor and manipulate infected systems without a conventional server. It obscures its communications by integrating with legitimate Telegram traffic, complicating detection. Upon execution, it creates a mutex to ensure only one instance runs and checks for debuggers to avoid analysis. It attempts to relaunch with elevated privileges and logs failures to its operator. ResokerRAT terminates known monitoring tools and installs a global keyboard hook to obstruct defensive key combinations. It operates through text-based commands sent via Telegram, allowing it to check processes, take screenshots, and modify system settings to evade detection. Persistence is achieved by adding itself to startup and altering UAC settings. The malware retrieves additional payloads from specified URLs and uses URL-encoded data for communication. Researchers have confirmed its Telegram traffic, and its behavior aligns with various MITRE ATT&CK techniques. Security teams are advised to monitor for unusual Telegram traffic and scrutinize registry keys related to startup and UAC.

Best antivirus for Windows 11: Guide to choosing the right software

Windows 11 provides a more secure environment than previous versions, but recovery remains a concern for users. Built-in protections are limited against threats like phishing and ransomware. The need for antivirus solutions has evolved to include comprehensive protection and recovery options. Basic threat prevention is often insufficient for home users and remote workers, who risk losing important files. Microsoft Defender offers a solid foundation, but products like Acronis True Image combine anti-malware capabilities with backup and recovery features. Antivirus software is essential for Windows 11 users, protecting against various malicious software. Modern antivirus programs offer real-time protection, web protection, and identity theft protection. Users must consider free versus paid solutions, as premium options typically provide advanced features. Top antivirus picks for Windows 11 in 2026 include Acronis True Image, Bitdefender Total Security, McAfee Total Protection, Norton 360 Deluxe, and Microsoft Defender Antivirus. Acronis True Image stands out for its dual functionality of prevention and recovery, utilizing AI-driven analysis to monitor unauthorized changes. Backup-focused alternatives like EaseUS Todo Backup Home and Macrium Reflect Home specialize in recovery but lack comprehensive antivirus protection. The choice between paid and free antivirus depends on whether Microsoft Defender meets users' needs. Paid suites generally offer deeper protection and advanced features. The best antivirus should provide robust protection while minimizing system impact, tailored to users' specific needs for prevention or recovery.

Which messaging app takes the most limited approach to permissions on Android?

Messaging applications Messenger, Signal, and Telegram exhibit significant differences in permissions and operational behaviors that impact user privacy. Telegram has the fewest total permissions at 71, with 25 classified as dangerous; Signal requests 72 permissions, including 19 dangerous ones; and Messenger requests the most at 87, with 24 dangerous permissions. Messenger also has the highest number of vendor-specific unknown permissions. Access to sensitive resources is crucial for messaging functionalities, with permissions for contacts, camera, microphone, location, storage, and calendar being essential. Telegram and Messenger request additional system-level permissions, while Signal is more conservative and does not request certain permissions like phone-call control or overlay windows. The analysis, using the Mobile Security Framework (MobSF), indicates all three apps are in the medium risk category, with Messenger having more flagged issues. Telegram allows cleartext connections by default, potentially exposing traffic, while Signal uses encrypted connections by default and only permits limited cleartext traffic for certificate checks. Messenger's issues include world-writable files and remote debugging enabled in WebViews. Messenger uses third-party SDKs, while Signal and Telegram do not disclose third-party trackers. All three utilize Firebase Cloud Messaging for notifications without sensitive data leakage. Data exchange patterns show Messenger primarily routes traffic through North America, while Telegram and Signal focus on Europe with some additional connections in the U.S. and Asia.

‘NoVoice’ Android malware on Google Play infected 2.3 million devices

A new Android malware called NoVoice has been found in over 50 applications on Google Play, with more than 2.3 million downloads. The malware targets older Android versions, specifically those patched between 2016 and 2021, and attempts to gain root access by exploiting vulnerabilities. It conceals malicious components within the com.facebook.utils package and uses steganography to hide an encrypted payload within a PNG image file. NoVoice avoids infecting devices in certain regions and has checks to detect emulators and VPNs. Once activated, the malware contacts its command-and-control server to gather device information and polls it every 60 seconds for tailored exploits aimed at rooting the device. It can exploit 22 vulnerabilities, including kernel bugs, and establishes persistence by replacing key system libraries and installing recovery scripts. The malware injects code into applications, particularly targeting WhatsApp to extract sensitive data for session replication, which is then exfiltrated to the C2 server. The malicious apps containing NoVoice have been removed from Google Play, but users who installed them should consider their devices compromised. Upgrading to devices with later security patches is recommended to mitigate the threat.
